| Abstract: | The synthesis of dibutyl sebacate with butyl alcohol and sebacic acid as reactants and sodium bisulfate as catalyst had been studied. The influent actors of reaction were investigated. The results showed that the appropriate conditions should be:Weight of catalyst was 0.2g(weight of sebacic acid if 0.05 mol);molar ratio of butyl alcohol to sebacic acid was 3 : l;the taking water reagent (Toluene) was 5 mL;the reaction temperature was 110-1401; reaction time was 1.0 h. The yield of dibutyl sebacate was about 98.6% . |
